April Meeting

We are the largest ham radio DX club in Arizona with over 140 members, many of whom are on the ARRL's DXCC Honor Roll.  We have several members who have traveled to distant places to put "rare" countries on the air.  We encourage any ham interested in DXing to join our club and learn about the many aspects of talking to hams around the globe who share this amazing hobby with us.  Founded in 1974, we are an ARRL-affiliated club and a member club of the Amateur Radio Council of Arizona (ARCA).

Our next meeting will be on Thursday night, April 6th at the PERA Club beginning at 7:00 pm.  The program will be presented by Carl Foster, KB7AZ.  Carl is coming up from Tucson where he is very active in our sister club, the Southern Arizona DX Association.  He will be talking about "stealth antennas", a subject near and dear to the hearts of many of our members who live in antenna restricted housing developments.  We will reverse the order of our meeting to accommodate Carl's flying schedule the following morning, so please get there by 7:00 so you don't miss his talk.

Please come and join us for the meeting and feel free to arrive early to socialize with your peers.  Refreshments will be served at the break.  Guests are always welcome.

March Meeting Recap

We have had some major league DXcitement these past two months with a number of big DXpeditions keeping the airwaves buzzing.  It has been an opportunity for many members to work an ATNO (all time new one) or to fill band slots for the DXCC Challenge.  Personally, I have been able to add a number of new countries to my totals on 80 meters and 160 meters. 

These expeditions have provided several examples of how gray line propagation can make a big difference in signal strength on both ends of a QSO.  The best one for me was 9G5X, the Brits who went to Ghana, a place I have visited in the past with the Voodudes.  They were not staying on 160m past our sunset, so I sent an email to one of the team members requesting that they pay more attention to west coast sunset.  That same night I listened as their signal came up out of the noise from S0 to S9 at our sunset making them workable from here.  They were as surprised as I was by the spike in signal strength, but it made a big difference to have them on for that gray line moment.

This signal peak is most pronounced on 80 and 160 for whatever reason, both at our sunrise and sunset as well as those of the DX station.  This is not true all of the time, but when it does happen, it is thrilling to witness.  I heard it again on 160 near our sunrise recently when T88XH was audible to me for the first time after several unsuccessful attempts to hear him during previous nights.

I hope many of you have 9G5X, TU7C, 5U5R, EA9/DL7DF, S21ZED or ZEE, and XX9D in your logs after this feeding frenzy.  Let's hope we have a few more brave souls go out on DXpeditions despite the lack of sunspots over the next few years.  It gives us all a reason to turn on the radio and cruise the bands looking for a "new one".

Our March meeting program was presented by Lee, KY7M, and Ned, AA7A, telling "The Safford Story".  They have spent the past nine months commuting to Safford to maintain and improve the remote station with 160 meter 8-Circle antenna built by Milt Jensen, N5IA, who died in a tower accident last June.

Lee described his first contact with Milt to operate in the January 2016 CQWW 160 CW Contest and how that led to his education about remote station technology.  As a result of the article he had published about that experience, Milt's family asked that he keep the station active as a way to preserve Milt's legacy.  That led to Ned's active involvement.

Ned described the many technical challenges they have had to overcome since taking on this responsibility.  He has redesigned the remote station's control systems and utilized additional remote technology to make using the station less onerous from four hours away. 

They both described some of the excitement they have experienced using the one-of-a-kind 8-Circle antenna and being a Top Band Beacon for stations around the globe.
